Hybrid tea rose plant named ‘Meibosnio’

ABSTRACT

A new and distinct variety of Hybrid Tea rose plant is provided which abundantly forms attractive very double blossoms that are a blend of yellow and salmon pink. The plant exhibits a bushy strong vigorous growth habit, dense dark green foliage, and excellent disease resistance particularly with respect to Black Spot. The attractive dark green foliage contrasts nicely with the light-colored blossoms. The new variety is particularly well suited for growing as attractive ornamentation in the landscape such as in parks and gardens.

SUMMARY OF THE INVENTION

The new variety of Rosa hybrida Hybrid Tea rose plant was created byartificial pollination wherein two parents were crossed which previouslyhad been studied in the hope that they would contribute the desiredcharacteristics. The female parent (i.e., the seed parent) of the newvariety was the ‘Meicloux’ variety (non-patented in the United States).The male parent (i.e., the pollen parent) was the product of the crossof the ‘Paloma Blanca’ variety (U.S. Plant Pat. No. 2,853) and the‘Bucbi’ variety (U.S. Plant Pat. No. 4,225). The parentage of the newvariety can be summarized as follows:

‘Meicloux’×(‘Paloma Blanca’×‘Bucbi’).

The seeds resulting from the above pollination were sown and smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It was found that the new variety of Hybrid Tea rose plant of thepresent invention possesses the following combination ofcharacteristics:

(a) exhibits a bushy strong vigorous growth habit,

(b) abundantly forms attractive very double blossoms that are a blend ofyellow and salmon pink,

(c) forms dense dark green non-glossy foliage that contrasts well withthe light-colored blossoms,

(d) exhibits excellent resistance to Black Spot, and

(e) is particularly well suited for growing as attractive ornamentationin the landscape.

The new variety of the present invention can be readily distinguishedfrom its parental varieties. More specifically, the ‘Meicloux’ femaleparent forms blossoms that display an orange blend coloration, the‘Paloma Blanca’ variety forms ivory white blossoms in clusters, and the‘Bucbi’ variety forms light pink blossoms that possess a pointedconfiguration.

The new variety well meets the needs of the horticultural industry andcan be grown to advantage in parks and gardens.

The new variety has been found to undergo asexual propagation in Franceby a number of routes, including budding, grafting, and cuttage. Asexualpropagation by the above-mentioned techniques in France has shown thatthe characteristics of the new variety are stable and are strictlytransmissible by such asexual propagation from one generation toanother.

The new variety has been named the ‘Meibosnio’ variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety were two years of age and were observed during Junewhile budded on Rosa froebelli understock and growing in outdoors at LeCannet des Maures, Var, France. Dimensions in centimeters are indicatedat the bottom of the photograph.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The description is based onthe observation of one year-old plants during October while budded onRosa froebelli understock and growing outdoors at Le Cannet des Maures,Var, France. The coloration in more common terms precedes reference tothe chart in some instances. Such terminology is to be accorded itsordinary dictionary significance.
